I tell ya, the AGM batteries from Deka are the $h!t!!! I got a brand new one from Chad, and it was a dud. I was having doubts about this battery, but met up with Chad, he swapped it out with no probs, and I have beat the hell out of this battery back and forth, side to side!! When my altenator went out I was heading to KY, I drove about 60 miles with headlights, heater, and stereo on til it dropped below 10 volts. Wouldn't even start the truck. By the time I took tha altenator off, went the store and got another one and installed in the truck (about 1.5 hrs) I didn't even have to charge or jump it off, had enough juice (from recovering) that it started the truck

I plan to get at least one more for my truck. With all the electronics and gadgets and lights and stereo I have in my truck, this battery has got me hooked!! Interstate batteries, junk, there commercial batts last less than a year. Optima, also junk, ever since the company that bought them out, they've went to $h!t...
Thanks again Chad
